You can manage to go up to Kaghan easily but onwards to Naran will create some problems. There are just a couple of hotels open now and the outside food restaurants are almost closed. If you want to surf in the daylight in Naran then you may plan it and rest the night in Kaghan. Else; the weather is so cold and chilling in Naran now. Let me tell you that I have just come back from Naran exacylt a couple of weeks before..
